The first deviation from [1]}'s method (described in Section REF ) is in the creation of a vector-based network (abbreviated to vb-network). For ease of description we denote this new vb-network as \(R_n^{\prime }(I)\)  to distinguish it from the high-weight version \(R_n(I)\) . We now define a vb-capacity in \(R_n^{\prime }(I)\)  which is of similar notation to that of a profile.
